With an average of 500 participants per event, WEO’s 2021 webinar series was enormously successful. Featuring relevant and cutting-edge science, each webinar attracted a large international audience and enabled critical discussion and an exchange of knowledge. If you were unable to attend, fear not! Recordings of all webinars – and of all WEO virtual events of 2021 – are freely available on both the  WEO website and the YouTube channel. Come and visit!
